Question

So, this is my function:

function thisismyfunction(myvariable) {
  // I do stuff here
}

And then if I wanted to run it, I’d assume something similar to this:

thisismyfunction('foo');

And then the argument is given. But what if it was something like this:

var myobject = new thisismyfunction;

Then how would the argument by given?

UPDATE: It seems that it is possible to instantiate it like this:

var myobject = new thisismyfunction('foo');

But is there another way which still can pass the value in?

Answer 1

If you use new then the parenthesis are optional so long as you aren’t passing arguments.

If you want arguments (that are not undefined), then they are required.

var myobject = new thisismyconstructor('foo');

Of course. I just said that.

But is there another way which still can pass the value in?

There isn’t any need for another way.
